I’m experiencing almost the same problem. My Apple Developer Program enrollment has been stuck on Pending since August 10. The $99 membership fee has not been charged, and I still haven’t received any activation email. I also opened a support case, but so far I haven’t received a meaningful response. Apple Developer Support Case ID: 20000134675095 Did Apple Developer Support ever reply to you or explain what is causing the delay? If they did, I would really appreciate it if you could share what they told you.
